A pulse radar range profile motion compensation method 10 comprises: acquiring receiver samples 12; acquiring an estimate of the range rate of a target 14; removing an additional phase acquired by the echo signals; removing a shift in range cells of the receiver samples 18; applying a pulse Doppler filter 22; identifying the peak Doppler frequency and calculating a shift from zero of the peak Doppler frequency 24; calculating a range rate correction 26; adding the range rate correction to the estimate of the range rate and repeating the removal of the additional phase 16 and the shift in range cells 18, and using the new range rate estimate to obtain motion compensated receiver samples 28; and generating an output signal indicative of the motion compensated receiver samples for generating a range profile 30.
